TRS 80 Color Computer 2

Boot screen and PRINTMEM. As you can see by the lower than expected memory (this is supposed to be a 16K machine), one of the 8040517 RAM chips is bad. The 16K Coco II did not use "regular" RAM like the more expensive Coco II.

The 32K Tandy Color Computer 2 model 26-3134B. This particular system has 16K with an extra 16Kb extended RAM. The 3134B model had an upgraded video compared with the Coco I and earlier CoCo II's.

The later Coco 2's like this one have the newer "Tandy" nameplate. The earlier CoCo 2 models still had "RadioShack" in their name.
